Dumb question how do I get progression points. I'm on ps4 and just want to unlock the a-3151.

Complete the maps challenge. Deliver loggs to the Lumbermill . Once both have their required amount of wood deliverd, a messege will come up with that games stats. 1 completed map is 1 progression point.
I hope this helps
